TO ALL WHOM ITIMAY CONCERN:

Be it known that I, W. P. LONG, of Wheatland, Knox county, State ofIndiana, have inrenteda new and useful improvement in the Forming ofSteel for the Construction of Ploughs; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make' and use the same, referencebeing had to the accompanyingdrawing, forming part ol"V thisspecification, in which- Figure l isa perspective view of a ploughconstructed according to my invention. i

Figure 2, a view ci" the metal plate out of which the plough isfermed,said plate being cut and prepared ready for bending and swaging intoproper form.

Similar letters ot' reference indicate like parts.

The object of this invention is to produce a single plate of steel oriron rolled or formed in such a manner that the plough when finishedwill he thicker at those parts where it is subjected to the most wear,and the plough be capable otbeing constructed at a very moderate cost.`To this end the invention consists in rolling a plate ot' steel or ironof taper or wedge shape transverselyfand then cutting said` plate ofdiamond or lozenge shape, and slitting the plate longitudinally thegreater portion of its length, and bending the plate so that the narrowpart formed bythe slit will be bent down to form the land-side, and theother part bent and swaged or rolled to form the mould-hoard or mainportion ofthe plough. A represents a plate of wrought iron or steel,which may beef any suitable dimensions, according to the size of ploughrequired. This plate is rolled so as to be transversely of taper form,as shown clearly in iig. 3, one edge, a, being more than double thethickness of the other, bl This plate is cutor slitted longitudinally,as shown at c, said cut extending from one end of the plate to withinsay six or eight inches of the opposite end. The cut c is near one edgeof the plate, the width of the narrow part dheing suicient to form theland-side, the mould'hoard being formed of the other parte. This plate,after being thus rolled, has its ends cut obliquely so as to be ofdiamond or Iozenge form, as shown clearly in g. 2, and the part d isbent down at right angles with the other part e, the plate in front ofthe cut c being bent diagonally from the cut to the thick edge, or atthe rear of-the end, as indicated by the dotted linef. The part e isthen b ent or swaged to form the mould-hoard, as shown in fig. l. Bythis mode of construction it will be se .n that the plough is quiteheavy or thick at those parts which are subjected to much wear. Theland-side is thick 'or heavy, requiring no rib, and the plough at thejunction 'of the land-side and mould-board is also heavy or thick, so asto wear a long time. The outer part of the mould-board, where there isnot much wear, `is comparatively thin. The ploughs maybe constructed inthis manner at a comparatively small cost, and they will be far more'durable than the plonglis of ordinary construction; there are no boltsto become loose, nor after work required, as is the case with theordinaryplonghs composed of two or more detached parts bolted together.

Having thus described my invention, what I-clai-m as new, and desire tosecure by Letters Patent,is- Forming'lthe land-side and mould-hoard fromone plate of metal, in the manner substantially as described,

for the purpose spceied.
